----------------------------------

             Summary: Javadoc for Consumer says that it's thread-safe
                 Key: KAFKA-2335
                 URL: https://issues.apache.org/jira/browse/KAFKA-2335
             Project: Kafka
          Issue Type: Bug
            Reporter: Ismael Juma


This looks like it was left there by mistake:

{quote}
 * The consumer is thread safe but generally will be used only from within a single thread. The consumer client has no threads of it's own, all work is done in the caller's thread when calls are made on the various methods exposed.
{quote}

A few paragraphs below it says:

{quote}
The Kafka consumer is NOT thread-safe. All network I/O happens in the thread of the application making the call. It is the responsibility of the user to ensure that multi-threaded access is properly synchronized. Un-synchronized access will result in {@link ConcurrentModificationException}.
{quote}

This matches what the code does, so the former quoted section should probably be deleted.
